Nice job Tyson. You're jumping in pretty fast actually. If I take a long time off it always takes me a few weeks at least before I can do anything remotely hard. Along those lines, it might actually be useful to do a longer/easier session here and there, say 170w for 60 mins (but I don't know what is the right wattage for you so this is just a guess -- the idea is to get a decent workout that's not too mentally taxing).
